PATENTO FFICE f V `MICHAEL J. MCHALE, oF scRAN'roN, PENNSYLVANIA ,YFLYER CONSTRUCTION Agpiicati'on filednay 31,

This invention relatesto- -iyers for spin` ning machines and; moreparticularly to one having .completely replaceable parts.

\ Hitherto it has been pro-posed to use `flyer passing therethrough. Inaddition,mill nuts or'` other like devices areoften required to hold thei'ye'r blocks in place on the spindles. Where selfcontaine 3lf` springsheld in place l5 by bushings have 4been used, thedisadvantage of' themrllnut has been obviated but the re-Wiring of such devices is, in everyinstance, a customjob;` Where devices of the typev shown in the patentto' E. Herr 2U #l,6l4,552 have been-used, vconsiderable dificulty hasbeen experiencedl withthe maintenance and repair ofthese devices, dnetothefact 1that'special tools Vare required for the assembling steps, inkorder to removeV broken' wires and replace them with new ones, and, inaddition, the. expansion anchoring sleeves frequently break and cannotbe replaced, thus requiring scrapping of the entirre unit.

Y y lit is an objectV of the `present, inventi'onto pro-vide a `iyer forspinning purposes which is composed of -aplurality ofv replaceableparts.-

It is anotherobject-ofv this invention to-v provide; an. improvedflyerofthe ltype described whichi's freely movable and pro videduwithreplaceable' parts throughout. 1

vReferring now tothe drawings, there'k is shown aconventional spooly orbobbin: 1. mounted on a spindle 2. The novel flyer of the presentiinvention, designated genera/lily as. 3,. is. mounted on the `spindle.and attached. thereto'Y by mean-sof springl member 4 whose. functionwill beaverted to more in :detail hereinafter. The flyer body of themember v 3 is preferably made of .any suitable metal such as brass,bronze or the like, the' several parts being machined-to shape orotherwise formed and comprises an upper portion. 5 and a lower portionV6L Member 5 comprises a cylindrical body portion having a `Centrallaperture 7 provided with ashoul'der portion n 8 adapted to retain springmember 4 in place.

The member 5 is provided with'flanges 9,1'0, the latter being adapted to'abut` against shoulder 11 ofmember 6. In addition, meinber 5 isprovided with a threaded extension 12, adapted toengage a correspondingfemale thread 133 in member y6.

The member 6 is provided with a central aperture 14 and an internallyshouldered portion 15 adapted to serve as a stop for member 5 whenscrewed in place. Integral with portion 11, the socket or casingA member6 is provided with an annular extension 16 adapted to receive flange 10of member 5. In addition, member-1G is provided with a plurality ofdiametrically positioned slots 17 having laterally extending portions 18adapted to receive sections 21 of flyer wires 20 and hold them inposition. lVhile the apertures 18 have been shown as substantiallyhorizontal they may of course be given any desired configuration asshown at 19 in Fig. 8' in which they are slanted downwardly and inwardlyfrom the aperture or slot The flyer wires 2O are provided with a centralsemicircular bowed portion 22adapted to engage or abut against section 7ot the fiyer holder and Vis further adapted to be locked in position inthe apertures 18 and/or 19. The flyer wires may be inserted in positionby passing the bowed portion 22 into the Y gap or space 23 formedbetween the abutting parts 5 and G of the flyerblock. After passing thebowed portion in this manner, a portion 21 of the wire is forced intoengagement with section 18 of the retaining slots and the oppositesection 21 of the same wire is forced into corresponding engagement witha like slot member. It will be seen that the leverage aiorded by thebearing of the portion 22 against the member 7 and of section 21 againstportion. 16 of the cooperating part ofy the flyer device will maintainthe members locked together due to the fact that the flyer, wireengaging flange 10 will prevent the unscrewing of the parts, thusserving as a. key or locking member.

When it is desired to unscrew the parts of the liyer block for anyreason it will be sufficient to force both of the flyer arms out ofengagement with their respective sockets and upwardly into slot 17 andout through aperture 23. As intimated hereinabove, a plurality of iyerwires may be applied, as is indicated in Fig. 4. In this instance, it ismerely necessary to provide the slot 17 in member`16 with oppositelypositioned' depressions or reentrant portions 18,19. rIhe flyer wiresare providedrwith the usual eyes 24, formed at the end of the dependingsections 25 of members 20. Owing to the fact that flyer wires wear outat the eyelet portions only under normal working conditions due to theabrasive action of the threads, the present invention.comprehends theidea of providing such sections of the flyer wires with a coating of anabrasion resisting metal such as chromium metal or the flyer wires maybe formed of a potentially hardenable metal which is manipulated andformed in the 1 usual manner after which the sections 24 may besubjected to any desired treatment whereby to give them a differentialhardness.

Referring now to the spring members 4, 1t will be noted that they arefreely movable within the central portion of the flyer block and areheld from axial movement by the shoulders 8 and 15 of the block. Thespring member 4, Vas above indicated, is adapted to engage spindle 2 andrevolve therewith the section 7 of the flyer block serving as a bushingor cage upon which the fiyer and itsassociated wires are adapted tofreely revolve about the member 4.

While a spiral spring construction may be used, the invention alsocomprehends the use of a coiled flat spring of the general type shown inFig. 9. This construction comprises a coiled spring 26havinga centrallyoffset portion 27, adapted to receive the ends 28, 29 of the spring andpresent a uniform internal and external diameter. q

It will now be appreciated that there vhas been provided an improvedflyer construction comprising a plurality of mutually interlocking partswhich are severally replaceable at will and which are characterized byahigh degree of mechanical efficiency as well as comparative ease Aofmanufacture and replacement. In addition, there has been provided animproved flyer wire having a Wear resistant section at the point wherenormal break down, due to abrasion occurs.

In accordance with the provisions of the patent statutes, Ihavedescribed the principles of operation of my invention, together with thedevice which VI now consider to represent a preferred embodimentthereof;.but I desire to have it understood that the device shown isonly illustrative of the basic concept of the present invention, andthat the said invention may be carried'out by other means.
